RAILWAY DRAFT-GEAR. YOKE.

memes. 1

Application filed February 25, 1920. Serial No. 361,679.

To call whom it may concern:

Be it' known that I, HARRY T. ANDERSON,

a citizen of the United States, and a resident of Butler in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Railway Draft- Gear Yokes, of which the following is a full, clear, and exact description.

The invention relates to railway draftgear yokes. Y

The object of'the invention is to provide an improved one-piece forged yoke.

The invention consists in the several novel features hereinafter set forth and more particularly defined by. claims at the conclusion hereof.

In. the drawings :Figure'l is a perspective of a railway draft gear embodying the invention. Fig. 2 is a detail perspective of the yoke. Fig. 3 is a plan. Fig. 4 a side elevation and Fig. 5 a horizontal section of the yoke. Fig. 6 is a section taken on line 6-6 of Fig. 1. Fig. 7 is a section taken on line 7-7 of Fig. 4.

The invention is illustrated as applied to a coupler 9 disposed between a pairof draftbeams 10 (only one of which is shown) a key 11 extending through the coupler shank and through elongated slots in beams 10, as well understood in the art a draft-gear 14 of any suitable construction interposed between the front and rear follower-plates 15 and 16, front stops 12 and rear stops 13, as well understood in the art, and the improved yoke.

Said yoke comprises integral sides 18 and 19 and a back 20 and is forged of a channeled bar comprising top and bottom flanges and a connecting web bent and doubled to form said sides and back, the flanges being brought, by such bending, into abutting relation. Adjacent the front end of each yokeside a transverse slot 25 is formed and the metal at the front of these slots is swaged or upset, as at 26, to reinforce the front-end of said slots, and the key 11 extends through these slots to secure the coupler shank and yoke together. Openings 30 are formed in the sides 18 and 19 and through the web of the channel bar, of which the yoke is formed. These openings are of suflicient length and height for the lateral insertion of the fol lower-plates 15 and 16 and the draft-gear 14. The front plate 15 is adapted to engage the web of the yoke at the front of openings Specification of Letters Patent. Patleniggd Deg,

30 andltherear plate 16 is adapted to engage the web at the back endof said open: ings.

In forging theyoke, theflanges of. the bar are brought together to form a substantially closed topand bottom for the yoke. If desired, the abutting edges maybe forgedtogether.v This forms a construction which is narrow and eflicient or strong. Those portions of the web of the bar which are dis posed in front of slots 30 are bulged outwardly beyond the planes of the upper and 7 lower edges of the yoke formed by the flanges' This provides integral portionsbetween which the coupler shank will fit and which form sides of the coupler shank pocket which are strong and which will form a very compactstructure; This is advantageous in getting the clearance, necessary in practice, Q,-

1 between the yoke and the draft-beams l0.

The method of forging the improved yoke is set forth in an application filed by me of even date herewith, and serially numbered 361,077.

The invention exemplifies a forged one: piece yoke with openings for the lateral insertion of the draft-gear and-follower plates, and in which the sides extend inwardly above and below the draft-gear into abut ting relation, thus forming a compact and eflicient structure and also such a yoke in which I the web-portions at the front end thereof-are bulged outwardly for advantageous connection to the coupler-shank. Y

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention. Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is: I

1. A one-piece forged draft-gear yoke comprising in combination a front portion have a 19D ing sides spaced apart to receive andformed for keying to a coupleieshank, a back, and longitudinal connecting members in: abutting relation between the back and-front portion, the yoke having openings adapted for the lateral insertion of the draft-gear.

2. A one-plece forged draft-gear yoke comprislngin comb natlon a front portion consisting of webs spaced apart to receive and 7 formed for keying to a coupler shank and '7 inwardly extending. abutting flanges above and below said webs, a back, and abutting top and bottom longitudinal connecting members between the front portion and the back, the yoke having openings for the lateral insertion of the draft-gear.

3. A one-piece forged draft-gear yoke comprising in combination a front portion, a back and longitudinal top and bottom connecting members between the front portion and the back, and having openings adapted for the lateral insertion of the draf -gear, the front portion having outwardly bulged sides formed to receive and formed for keying to a coupler shank.

il. A one-piece forged draft-gear yoke com- 'prising in combination a front portion, a

back and longitudinal top and bottom connecting members between the front portion and the back, and having openings adapted for lateral insertion of the draft-gear, the front portion consisting of webs and inwardly extending top and bottom flanges, the webs being bulged outwardly of the flanges and formed to receive and for keying to a coupler shank.

5. A one-piece forged draft-gear yoke comprising in combination a front portion, a back and longitudinal top and bottom connecting members between the front portion and the back, and having openings adapted for the lateral insertion of the draft-gear, the front portion consisting of webs and inwardly extending top and bottom. flanges, the webs being bulged outwardly of the flanges and formed to receive and for keying to a coupler shank, the connecting members being also formed or" inwardly extending flanges.

6. A one-piece forged draft-gear yoke comprising in combination a front portion, a back and longitudinal top and bottom connecting members between the front portion and the back, and having openings adapted for the lateral insertion of the draft-gear, the front portion consisting of webs and inwardly extending top and bottom abutting flanges, the webs being bulged outwardly of the flanges and formed to receive and for keying to a coupler shank. V

7. A one-piece forged draft-gear yoke con1- prising in combination a front portion, a back and longitudinal top and bottom connecting members between the front portion and the back, and having openings adapted for the lateral insertion of the draft-gear, the front portion consisting of webs and inwardly extending top and bottom abutting flanges, the webs being bulged outwardly of the flanges and formed to receive and for keying to a coupler shank, the connecting members being also formed of inwardly extendmg abutting flanges. v
